aws nat gateway charges you twice for the same packet. once at $0.045/hr just to exist (~$33/mo per gateway), and again $0.045 for every gigabyte it moves.
the hourly fee is visible so nobody worries about it. the per-GB fee is the one that quietly grows, because it rides on traffic you never watch — docker pulls, apt installs, s3 reads from private subnets.
open cost explorer, group by usage type, look at NatGateway-Bytes. that's the number to chase.
